To all whom it may conccm:

Be it known that I, IvAR PETER BAGGER KNUDsEN, director a subject oiDenmark, residing at Ne. 56 Ivanemllevej, in the city oi Copenhagen andKingdom of Denmark have invented new and useful Improvements in Bearingsor Rapidly-Rotating Bodies, oi which the following is a speciiication.

This invention relates te a bearing tor rapidly rotating bodies arrangedinsuch manner that it will allow the body supported by it to rotate onthe aXis passing through the center of gravity, while at the same timeit has a constant tendency to center the body during the rotation. v Bythis means the shocks and vibration which would otherwise occur duringthe rotatien, are diminished to a great extent or are praeticallyeliminated, so that the running oi the machine is rendered much steadierthan otherwise, while its durability is considerably increased.

A constructional form ot the invention is illustrated in theaccompanying drawing in which Figur-e l is a vertical central sectionthrough the bearing, and Fig. 2 is a horizontal section on line A-B oiFig. 1.

The pivot member of the rapidly rotating body is indicated by a, while bindicates the casing provided for the hearing in the iraming oi themachine. In this casing there is screwed a box c having at its upper endan annular flange d which encircles the member a with a suitableclearance space between the two.

An annular disk g of suitable material is arranged between the flange dand an annular plate e or the like which is placed loose in thecylindrical bore oi the box c and which is pressed by means of one ormore springs f against the fiange d. This disk g encircles and supportsthe member a and its outer diameter is somewhat smaller than thediameter ot the bore ot' the box c so that it is capable of yieldingwhen the pressure exerted by the member is so great that it can overcomethe triction between the disk and the surface between which it is firmlyclamped.

A spiral spring i is arranged in an annular recess h provided in theouter surface et the disk g. This spiral spring 'i bears against theinner wall ot the box c and has a constant tendency to center the disk gand, along with the latter, the member a.

i l i i i i i i i i The above described arrangement has tor efiect torender the running oi the body steady and even in consequence oi theiact that all shocks and vibrations are taken up by the disk g which isclamped iast between the two suriaces. This disk, while overcoming theirictienal resistance between it and the surface, yields to the pressureoi the member a without producing sudden reactional strains, because themember must alwaysagain overcome the atoresaid irictional resistance; atthe same time the spring i has a tendency to return the pivot memberinto the normal or central position.

The Construction shown may obviously be modified without departing fromthe principle oi the invention.

Having now described and ascertained the nature oi" my said inventionand in what manner the same is to be performed I declare that what Iclaim is'.

l. In a hearing for a rapidly rotating body, the combination With thepivot member of the body, of a disk encircling the pivot member anddisplaceable therewith in a direction transversely of the axis of thehearing, a spring tending to maintain the disk and pivot member in acentral position, and members having surfaces between which said disk isclamped in such a manner as to cause frictional resistance to beoiteredto movements of the disk transversely of the axis of the bearinsubstantiaily described,

2. ln a hearing 'for a rapidly rotating body, the combination with thepivot member of the body, of a disk arranged to move with the pivotmember transversely of the normal axis of the pivot member, a pair ofmembers having surfaces between which the disk is clamped in such amanner to cause frictional resistance to be offered to the transversemovement ot' the disk and the pivot member, and yielding means tendin;to center the disk and the pivot member.

3. In a hearing for rapidly retating hodies, the combination with thepivot member of the body, of a disk encircling and supporting the pivotmember, arranged to move against frictional resistance transversely ofthe axis of the pivot nemher and provided With an annular recess, and aspring arranged in the rccess in the disk and tending to center the diskand the pivot member.

In testimony whereof I have signed my name to this speeification in thepresence of two suhscribing witnesses.
